How to combine tree and wc -l?

Question

I have folder base_dir with subfolders, each subfolder contain .jpg images, I want output similar to tree -L 1 base_dir, but with number of jpg images next to subfolder name, is it possible?

Answer 1

This will output somwhat similar:

find  base_dir -mindepth 1 -maxdepth 1 -type d -print0 | 
xargs -0 -n1 sh -c 'echo "$1 $(find "$1" -name "*.jpg" | wc -l)"' --

For each directory in base_dir output the directory name and the count of files named *.jpg. Example output:

base_dir/b 2
base_dir/a 1
base_dir/d 3
base_dir/c 0
